Fix two warnings by removing unused code

Fix these warnings:

fs/fsys_cramfs.c: In function 'cramfs_read':
    fs/fsys_cramfs.c:206:7: warning: variable 'devread_ret' set but not used [-Wunused-but-set-variable]
    fs/fsys_cramfs.c: In function 'cramfs_dir':
    fs/fsys_cramfs.c:295:6: warning: variable 'namelen' set but not used [-Wunused-but-set-variable]

by removing the assignments and one unused call to strlen().
